Hi,
Please clean the cache and check if the issues are still present:
$ rm .cache/gstreamer-1.0/registry.aarch64.bin
From the error print:
WARNING: erroneous pipeline: could not set property “SliceIntraRefreshInterval” in element “nvv4l2h265enc0” to “15!”
It seems like the properties are not correctly read. It should be read as “15” but it shows “15!”.
And for rate control, we would suggest set CBR + virtual buffer size. Please refer to this topic:
